Last time I used JZM which is a fair while ago they were 10% less than an OPC….I’d go to an OPC in that instance !

In addition the savings are because they use OEM from Design911 instead of Porsche parts (unless you request Porsche parts).

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi All I am coming to the end of my Porsche warranty life span - the 15 yr mark. Actually it is 14 yrs in October 2026 but I cannot extend it for another year because it runs from August to August. Go figure. So time to switch to a Porsche specialist. The car is a 991.1 C2S. I completed the 12 year service at Porsche in August and I am looking for a cracking Porsche specialist in the Hertfordshire area. I like to change the oil every year so this seems a good time to find a good specialist. I have had a look at JAZ Porsche. They seem to have a good set up and have been around for a while but not many reviews on Google. I have also noticed AMS. They have a lot of positive reviews. I am aware of Friends Green Porsche as well. They seem like a young set up but their videos do demonstrate a professionalism. JZM are as expensive as a Porsche main dealer which defeats the purpose. Can anyone suggest someone they have used consistently over a few years. Thanks

POST 3Original post

RPM Technik are excellent and my preferred choice - but no courtesy car, although they will happily drop you at the train station. JZM also good, and decent courtesy cars if you book early. JAZ also a decent set up and very knowledgeable, especially with the earlier stuff. These are just the ones I have experienced.

POST 4Original post

Another vote for the team at RennWorks they look after our cars

POST 5Original post

Just go to the nearest specialist to you as they end up being much of a muchness Though have a look at friends green porsche review on 911uk and decide from there unless thats what you meant about being aware of them

POST 6Original post

Personally wouldn’t go to JAZ with a 991.1 Out of RPM and JZM which I have used both more than once it would 110% be RPM.

Cheib said: Personally wouldn t go to JAZ with a 991.1 Out of RPM and JZM which I have used both more than once it would 110% be RPM. But RPM charge Porsche main dealer levels of labour rates.

I d agree with that Hey All Thank you for all the feedback. I agree that JAZ do focus on the earlier stuff. I think FGP are still too young and experienced ex Porsche mechanics are what I am looking for. JAZ and RPM charge OPC rates so I don't see the benefit. I have come across https://www.porschespecialistservices.co.uk/ who are based in Chelmsford. They have outstanding reviews and are part of the Porsche network. In addition the savings are because they use OEM from Design911 instead of Porsche parts (unless you request Porsche parts). The whole point of the specialist is about being smart with your money. Has anyone used them? Edited by FrancisA on Thursday 25th June 10:28

wax lyrical said: Cheib said: Personally wouldn t go to JAZ with a 991.1 Out of RPM and JZM which I have used both more than once it would 110% be RPM. But RPM charge Porsche main dealer levels of labour rates. I thought RPM’s labour rate was circa £130 ? Porsche Silverstone is £240 ish. Last time I used JZM which is a fair while ago they were 10% less than an OPC….I’d go to an OPC in that instance !

POST 11Original post

Another vote for Rennworks. Been using them for 5 years with a 997.2 and very happy.

POST 12Original post

Based on the quotes posted here over a few years, OPC and specialist service charges can be broadly similar until you start needing extras like spark plugs, belts. No way I'd be schleping it to another county though unless it's near a place that's more convenient for work. There are plenty of decent specialists in the South East, with several in HERTS
